Home page won't load

Hi, I recently converted my wordpress to multisite. Everything went smoothly (eventually!) except for my blogs-mu home page. The page only loads the headers with the #header div empty, even though I have all the info filled out. Also, the buddypress admin bar isn't loading on the home page.

It was working fine before the switch to multisite. Every other page loads perfectly, including the buddypress admin bar.

My guess is it's something simple, but I have no idea what. Please HELP!
